The Traceable Radiometry Underpinning Terrestrial- and Helio-Studies mission (TRUTHS) is a planned European Space Agency (ESA) satellite.It is meant to "improve the accuracy, reliability and integrity" of Earth observation (EO) data, [2] and to be the first of a new class of "SI-traceable satellites" (SITSats) that will enable other EO missions to calibrate measurements with reference to them.
A calibration curve plot showing limit of detection (LOD), limit of quantification (LOQ), dynamic range, and limit of linearity (LOL).. In analytical chemistry, a calibration curve, also known as a standard curve, is a general method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration.

The Joint Committee for Traceability in Laboratory Medicine or JCTLM is collaboration between the International Bureau of Weights and Measures (BIPM), the International Federation for Clinical Chemistry and Laboratory Medicine (IFCC), and the International Laboratory Accreditation Cooperation (ILAC).
Certified reference materials (CRMs) are 'controls' or standards used to check the quality and metrological traceability of products, to validate analytical measurement methods, or for the calibration of instruments. [1] A certified reference material is a particular form of measurement standard.
A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.
AFMETCAL (Air Force METrology and CALibration Program Office), located in Heath, Ohio is the primary manager of metrology services for the U.S. Air Force.It retains engineering authority for all calibrations performed in the PMEL labs throughout the Air Force, and oversees the contractor managed and operated Air Force Primary Standards Lab (AFPSL).
Spanish authorities said on Monday they had seized seven tons of cocaine stashed in sea freight containers buried underneath a farm, arresting three suspected smugglers. Police posted video of the ...
Within a product's supply chain, traceability may be both a regulatory and an ethical or environmental issue. [3] Traceability is increasingly becoming a core criterion for sustainability efforts related to supply chains wherein knowing the producer, workers and other links stands as a necessary factor that underlies credible claims of social, economic, or environmental impacts.
